Application filed January 7, 1910. Serial No. 536,803.

To all whom it mast concern:

Be it known that I, CHARLES S. Locxwoon, a citizen of the United States,residing at 289 Market street, Newark, county of Essex, and State of NewJersey, have invented certain new and useful Improvements inRoller-Bearings for Side and End Strains, fully described andrepresented in the following specification and the accompanyingdrawings, forming a part of the same.

This invention relates to a roller bearing having a conical hub with aseries of conical rolls fitted thereto, and a casing having a taperingseat to embrace the outer sides of the rolls. Such a bearing isoftenemployed to resist lateral strain, but any such strain tends to crowdthe rolls toward the larger end of the seat within the casing and tothus force the hub endwise. This is a very objectionable feature wherethe casing is held immovably and the shaft having the hub is providedwith parts which are intended to maintain a fixed relation to otherparts, as any movement of the hub endwise tends to derange the relationof such parts. Various constructions have been devised to resist suchend movement of the hub, and the construction claimed herein is for aparticular organization in which. a collar is formed upon the larger endof the hub to receive the end thrust of the rolls, and a ball-ring isfixed adjustably in the larger end of the casing and balls inserteddirectly between the same and a bearing-ring having a ball-race fixed tothe outer end of the hub.

The invention will be understood by reference to the annexed drawing, inWhich-- Figure 1 is a longitudinal section, where hatched, of a bearingembodying the invention; Fig.- 2 is an end View of the ball-ring whichis fitted in the open end of the casing, and Fig. 3 is an elevation ofthe hub.

The casing a is shown cylindrical to be held in a socket when in use,and has a tapering seat 6 at one end and'a shell a extended toward theother end with a chamber 0 inside of the same, in which an adjustableball-race is secured.

The hub has a conical seat f with collars h and w respectively at itssmaller and larger ends, and the tapering rolls 9 are fitted to theseats 6 and f, and are made of'such length as; to touch the collars hand w. A cage Z is shown to guide the rolls'in their movement upon theseats. The hub is shoul one end and a shell fixed rigidly upon and aball-ring secured to the shell with-balls dere'ol down at its largerendand a bearing rmg having a ball-race is is fitted thereto, and inpractice is made larger than the collar to.

By making the ball-race separately and fitting it upon the hub, acheaper construction is secured, as the hub is commonly made from solidstock, and stock of such greater'diameterwould be required if theball-race were made integral therewith.

The shell a is threaded upon its inner side and a ball-ring n suchthread, and is formed with a circular flange 8 provided with radialtap-holes t. A

screw 4) is shown inserted through a slot at in the edge of the shellthe ball-ring.

ball-ring n and ably grooved to ring is adjusted the screw-thread intoone of the holes t in The adjacent faces of the ball-bearing-ring k aresuitadmit balls at, and the ballin the casing by means of when all theparts are as-.

is fitted to screw within 1 sembled, so as to hold the rolls in snugcontact with the seat 6 in the casing. When the ball-ring is thusadjusted, the screw 1: is inserted in oneof the holes t, thus keepingthe ball-ring lockediirposition.

With this construction, it will be seen that all the endthrust duced bylateral strain upon the bearing is confined to the casing, as the shella forms a connection between the seat 6 for the rolls and the ring a forthe balls. The tendency of the rolls to push the hub endwise whensubjected to lateral strain is thus resisted by the fixtures in theopposite end of the casing, and the hub is held securely from endmovement.

Having thus set forth the nature of the invention what is claimed hereinis:

1. A self-contained roller bearing, consistupon the hub which is proingof a casing ahaving a tapering seat 6 in a upon the other end, a conicalhub arranged within the casing and having a conical seat. f with annularshoulder w at its larger end, a series of conical rolls 9 fitted to theseats upon the casin and hub with their larger ends against the sliouleder w, a bearin -1 'ing.hav1ng a ball-race the larger end of the hubfitted directlybetween such ball-ring and the lob ball-racebearing-ringlc to resist end move.

mentof the hub within the casing. 2. The combination, with a casing ahaving. an interior tapering seat I; with a'shell a ex" ended therefromand threaded internally, of a conical hub havin a conical seat 1 withannular collar 'w at its ar er end, a series of conical rolls g fittedto t .e seats upon the casing and hub with their larger ends against thecollar w, the separate bearingrin having a ball-race k fitted to the hubagainst the collar w, and the ball-ring n fitted to the screw-threadwithin the shell and secured therein when adjusted, with balls betweensuch ball-ring and the ball-race bearing-ring is to hold the hub inposition within the casing.

3. A self-contained roller bearing, consisting of a casing a having atapering seat I) in one end and a shell (1' u on the other end, aconical hub arranged within the casing and having a conical seat 1 withannular collars k and w at the smaller and larger ends of the seatrespectively, a series of'tapering rolls fitted to the seats upon thecasing and hu and having their ends contacting with the said collars, aball-race-bearing-ring 7a fitted to the hub in contact with the collarw, and a ball-ring secured to the shell with balls fitted directlybetween such ball-ring and the ballrace bearing-ring k, to resist endmovement of the hub within the casing.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
